Southern cars should use 5W/30 or 5W/40 engine oil. Functions of engine oil: Automotive engine oil serves to lubricate, clean, cool, seal, reduce friction, prevent rust, and protect against corrosion in the engine. Engine oil determines the lifespan of the engine: The engine is the heart of a car, containing many metal surfaces that move and rub against each other. These components operate at high speeds, in harsh environments, and can reach working temperatures of 400°C to 600°C. Under such extreme conditions, only qualified lubricating oil can reduce wear on engine parts and extend their service life.

Why doesn't the fuel gauge display after refueling?

The reasons why the fuel gauge doesn't display after refueling are: 1. Fuel float failure; 2. Computer signal failure; 3. Instrument damage. The fuel gauge consists of a fuel level indicator with a voltage regulator and a fuel level sensor. Its function is to immediately illuminate an alarm when the fuel in the tank is less than a specified value to alert the driver. Precautions for using the fuel gauge are: 1. Do not wait until the warning light comes on to refuel; 2. It is not recommended to fill the tank completely when refueling. The method to check the fuel gauge is: 1. When the illuminated bars reach the F position, it means the tank is full; 2. The closer the illuminated bars are to the E position, the less fuel remains, and it's time to refuel promptly.

What is the Function of the Oil Ring?

About the specific introduction of the oil ring function is as follows: 1. The specific function of the oil ring. The main function of the oil ring is to scrape off the excess oil splashed onto the cylinder wall during the downward stroke, preventing the excess oil from entering the combustion chamber and participating in combustion; during the upward stroke, it applies a uniform oil film on the cylinder wall to reduce the wear of the piston, piston rings, and cylinder. 2. Classification of oil rings. The oil ring is a type of piston ring, divided into ordinary oil rings and composite oil rings. The structure of an ordinary oil ring is made of alloy cast iron, with a groove cut in the middle of the outer circular surface, and many small through oil drainage holes or slits processed at the bottom of the groove; while the composite ring consists of upper and lower scrapers and a spacer spring that generates radial and axial elastic forces. The oil ring scraper is very thin, with a high specific pressure on the cylinder wall and strong oil scraping ability.
